These organisms transform light energy, carbon dioxide, and water into sugars, which allow them to grow their bodies, reproduce, and be a source of energy for other organisms. Studying photosynthesis in nature and in the laboratory has given scientists important insights into the effects of climate change on plants and other photosynthetic organisms. For example, such studies help scientists understand whether there will continue to be enough food for humans to eat as the climate changes. In this article, we discuss the importance of photosynthetic organisms; how light energy, carbon dioxide, and water are transformed into sugar during photosynthesis; the challenges that today’s land plants face; and how and why scientists measure photosynthesis in plants.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"4 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141701167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is believed to be the oldest and most biodiverse lake in Europe. Several hundred meters of sediments have built-up on the lake bottom since its formation. These sediments are a record of what happened both within the lake and in its environment in the past. Therefore, Lake Ohrid is a unique place to learn more about Earth’s history. Drilling down into the lake bottom to get samples of sediment layers allowed us to unravel the secrets of the lake’s history. The sediments revealed that the lake formed between 1.9 and 1.4 million years ago. They showed past environmental and climate changes in the Mediterranean region. Tiny fossils showed the evolution of the lake’s biodiversity in the past, which benefitted from the lake’s long and stable existence. The stability of Lake Ohrid’s ecosystem is now threatened by increasing human impacts. Protecting this unique place is needed.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"33 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141107066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the pandemic also taught us some key lessons. We learned that it is important for scientists and doctors to work together closely to understand health threats. Collaboration led to fast production of a safe, effective, COVID-19 vaccine. We learned that diseases can quickly spread all over the world, which taught us about the need for global cooperation and equal access to vaccination and other health services. The pandemic also showed us how critical it is to understand health information, so that we can tell accurate information apart from false claims. These lessons will shape our future, hopefully leading to even greater advances in science and healthcare that will create a healthier world.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"51 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141103070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Just as various construction trades must work together to build a skyscraper, scientists from separate fields can cooperate to tackle complex scientific challenges. This is called interdisciplinary collaboration, and it is a great way to do science. By bringing together knowledge and tools from multiple fields, scientists can uncover creative solutions and make meaningful connections that they might not have reached on their own. We give an example of how collaboration between particle physics and medicine—two fields that seem very different from one another—come together to improve healthcare. Using the tools of particle physics, scientists are enhancing cancer diagnosis and treatment. Interdisciplinary collaboration is the best way to address many of the complex issues we face today, like controlling climate change or fighting cancer, and it can help scientists and doctors make a lasting impact on human lives and the health of our planet.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"45 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141113798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers have discovered some situations in which the brain can be “fooled”, and these insights into the brain’s inner workings have led to some exciting new technologies, including virtual reality (VR). In addition to its well-known role in gaming and entertainment, VR has some amazing uses in the field of medicine. VR can help patients manage pain, and it can also help surgeons practice delicate procedures and guide them during operations. Other advances called brain-machine interfaces can listen to the brain’s chatter and translate thoughts into commands for computers or even robotic limbs, which could greatly improve the lives of people with certain disabilities. In this article, we will explain how researchers are using findings from cutting-edge brain research to produce exciting new technologies that can heal or even enhance the brain’s functions.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"7 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141117717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Norway, cows roam freely in the deep forest during summer. While the cows enjoy the freedom, it can be tricky to keep them safe from carnivores like wolves and bears, as no shepherds or dogs protect the herds. Keeping an eye on the cows is important! Farmers and researchers use GPS to track animals, just as we do for phones or cars. However, GPS does not tell us much about what the animals are doing. That is where movement sensors come in. These sensors store information about the tiniest body movements and reveal what the animal is doing at any time. Is the cow’s head up or down? Is it walking or running? Based on the data, we could distinguish 20 different behaviors! Now we can spy on cows, see what they are up to in the forest, and help farmers better care for them.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"121 30","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140370342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salmon farming is a big industry, providing food for millions of people every day. However, the journey of this delicious meal from the ocean to your plate depends on lumpfish, a cool-looking fish that protects farmed salmon by eating sea lice. Sea lice are small parasites known to attack salmon and can cause disease if not removed. Since lumpfish are vulnerable to diseases, it is crucial to understand more about this organism’s complex immune system, as this will help keep them healthy so they can then do their important “job” of eating sea lice. In this article, we will explain how we study the way the fascinating lumpfish defends itself against diseases.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"137 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140369460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But have you heard that wasps perform really important services in nature, such as pest control and pollination, and that they can also serve as living indicators of environmental health? We can learn a lot from wasps. Most people do not know that wasps have a sophisticated communication system—they use their eyes to see, their antennas to smell, and their legs to feel vibrations. The bodies of adult and young wasps are covered by a mix of odors, which carry information about which family they belong to. We decided to do experiments to see if wasps can recognize their eggs because, to us, all wasp eggs look very similar. In this article, we will show you that wasp eggs carry odors that wasps can recognize, and this helps the entire colony to function properly.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"4 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140375218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This water melts and thins the ice shelf, and speeds up the rate at which ice moves into the sea, leading to sea-level rise. Scientists often get on board ships called icebreakers to study the ice and water in these regions. However, sea ice and icebergs are major obstacles to navigation and scientific operations. For example, American, Australian, and Japanese icebreakers tried but could only observe a small area where sea ice was more broken up. So, we used a helicopter to measure the ocean during one of our research expeditions. Helicopters can travel faster than icebreakers. They can fly over sea ice and icebergs, and trained workers can drop sensors into small gaps in the ice. In 6 days, we observed ocean temperatures at 67 sites, covering a large area that could not be studied before. We identified wide pathways of warm water flowing toward the Totten Ice Shelf.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"18 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140374056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MPS contain human cells carefully arranged to simulate a real organ’s structure and function. One type of MPS, called an organ-on-chip, also pumps fluids containing nutrients and oxygen through the model, similar to the function of blood flow in our bodies. These MPSs can test how medicines affect human cells and help scientists develop safer, more effective treatments for diseases. MPSs can also be personalized using a patient’s own cells, to find the best treatment for each person. While challenges remain, like cost and reliability, MPSs are steadily improving. Beyond testing medicines, they can be used to study dangerous environmental chemicals and to model diseases. We can even connect multiple “organs” to simulate the whole body. As these revolutionary technologies improve and become widely accepted, they could speed up drug development and reduce animal testing.","PeriodicalId":73060,"journal":{"name":"Frontiers for young minds","volume":"98 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140377455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
